Ensaios preliminares em laboratório para o controle do manhoso, Chalcodermus bimaculatus Fiedler, em feijão-de-corda, Vigna sinensis Endl., com inseticidas orgânicos sintéticos

Abstract

The preventive action of Endrín, Diazinon, Toxaphene, Chlordane and Malthion was studied for the control of Chalcodermus bimaculatus Fiedler, in cowpeas, Vigna sinensis Endl. The Endrin and Diazinon had good lethal and repellent action. The Taxophene and Chlordane had only repelent action. The Malathion did not have a lethal and repellent action
